Abstract: A system and method for adjusting the frequency of operation of a radio frequency circuit including an inductive loop having an adjustable exposed inductor portion is provided. The frequency of operation of the circuit is first detected with means for detecting a parameter relating to and representing the frequency of operation. The adjustable inductor portion is associated with a selectively movable actuator device coupled to the frequency detecting means and a source of signals representing a predetermined frequency of operation for the circuit. A control circuit means, preferably a computer, is coupled to the detecting means and to the source of signals to provide an output control signal when the detected frequency of operation bears a predetermined relationship to the predetermined frequency of operation.

Abstract: A piezoelectric assembly with a flexible circuit interconnect is provided. The flexible circuit interconnect is comprised of a first flexible insulating base film including spaced electrically conductive circuit traces, a second flexible insulating film disposed over a portion of the first base film and a segment of the traces, and means for electrically connecting the traces to an electrical circuit. Also provided is a method for manufacturing a flexible circuit interconnect for a piezoelectric element comprising laminating spaced circuit traces on a flexible insulating base material to define a contact arrangement with a first set of terminal ends of the traces; attaching termination electrical connectors at a second set of terminal ends of the traces; mounting an insulating overlay to the base material for insulating a portion of the traces and electrical connectors; and, mounting a piezoelectric element to the contact arrangement.
